WRENCH.

s'PEoI'FIcA'TIoN forming part of Letti-r Patent No. esjme, dated october 2, leo. Application filed Jantiafy 25, 190D. berial No. 2,776. (No model.)

To a/ZZ whom it may con/cern? l Be it known that I, WILLIAM D. BEcH'rEL, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to new and useful improvements in wrenches; and its primary object is to provide a combined pipe and nut wrench of simple and durable construction which may be readily adjusted.

To `these Vends the invention consists in the novel construction and combination of parts hereinafter more fully defined and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a side elevation of the wrench, and Fig. 2 is a section therethrough.

Referring to said figures by numerals of reference, 1 is the shank of the wrench, having a jaw 2 formed on or secured to one end thereof, said jaw preferably comprising oppositely-extending portions 3 and 4, adapted for use as a nut and pipe wrench, respectively. Within one of the edges of the shank 1 are formed teeth or serrations 5 for the purpose hereinafter described. Slidably mounted upon the shank is a sleeve 6, recessed at one side, as at 7, for the reception of toothed block 8, to which is pivotally secured a thumbscrew 9, adapted to engage with a plate 10, secured over the recess 7 by means of screws 11 or in other suitable manner. To both sides of the sleeve 6 is pivoted a lever 12, adapted to inclose three sides of the shank 1, but normally removed therefrom by, preferably, a bow-spring 13', secured to the lever 12 and bearing upon the shank.

The forward ends 14 of the lever 12 are enlarged substantially as shown, and each of said ends is provided with two slots 15,formed in arcs eccentric to the pivot 16 of the lever, and each slot adapted to receive one of four pins 17, projecting laterally from the opposite faces of a sliding jaw 18, mounted upon the shank 1 and extending in opposite directions, as shown, one end portion 19 thereof projecting forward and adapted t0 be received by the portion 4 of the pipe-wrench when the jaws are closed.

In operation when it is desired to adjust the wrench to flt either a pipe or nut the thumbscrew 9 is turned so as to withdraw the block 8 from engagement with the teeth 5 of the shank. The sleeve 6 is then slid the desired distance upon the shank, carrying with it the sliding jaw 18 and the lever 12. The screw 9 is then turned in the opposite direction until the teeth of the block are brought into' engagement With the shank, securely locking the sleeve in position. The lever 12 is then pressed toward the shank 1, the slots 15 near the end thereof forcing the pins 17 and the jaw 18 slightly forward, as is obvious;

It will be understood that the jaw 18 will be retracted when pressure is removed from the lever 12 and the same is pressed back to its normal position by a spring 13.

While I have shown my invention as applied to a combined pipe and nut wrench, I do not limit myself thereto, as the same is equally applicable to single wrenches.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modification may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having-thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A wrench comprising a sleeve; a toothed shank formed with a xed jaw and extending through, and slidably mounted within, the sleeve; a toothed blockl within a recess in the sleeve and adapted to engage the teeth of the shank; a plate detachably secured to the sleeve and adapted to retain the block in position; an adj usting-screw mounted in said plate and secured to the block; a lever pivoted to the sleeve and adapted to inclose the shank; an enlarged end to the lever having similar slots therein arranged eccentrically to the pivot of the lever; a jaw slidably mounted upon the shank; and pins projecting from the sliding jaw and adapted to be received by said slots, whereby the jaw is operated bythe movement of the lever.

In testimony whereof I affix my signature in presence of two witnesses.
